I am sorry, but this is not possible. The passport has security features that make it easily detectable to alter. Even untrained people would see the alterations.
In addition, this would be a federal offense since the passport is not your property. It is the property of the Federal Government. Altering it could result in heavy fines and imprisonment. Even with a small fine you would have a federal conviction.
The fed is funny that way.
People in the military who are late to work can end up with a federal conviction if they choose a court martial.
If you get a traffic ticket and appeal it from the federal magistrate, you go up to federal court.
NO, you really cannot alter your passport. That is too serious an offense.
